Control of the Alphitobius Diaperinus (Panzer) (Coleoptera: Tenebrionidae) with Entomopathogenic Fungi
The beetle Alphitobius diaperinus (Panzer), considered a worldwide pest in the poultry industry, is difficult to control and it is a vector for pathogens. The objective of this study was to evaluate the biological control of the lesser mealworm, by strains of fungi Beauveria bassiana, Cladosporium sp. and Trichoderma sp. Larvae and adults of the A. diaperinus were inoculated with suspensions of...
متن کاملThe acquisition and internalization of Salmonella by the lesser mealworm, Alphitobius diaperinus (Coleoptera: Tenebrionidae).
In poultry broiler production facilities, it is important to understand the sources and contribution of reservoir populations of pathogens. The lesser mealworm beetle, Alphitobius diaperinus (Panzer), is a common pest in poultry litter that is reported to carry pathogens affecting both human and animal health. This study investigates whether the carriage of a bacterial pathogen occurs by the ha...
متن کاملEvaluation of Salmonella movement through the gut of the lesser mealworm, Alphitobius diaperinus (Coleoptera: Tenebrionidae).
AIMS The lesser mealworm, Alphitobius diaperinus is an important poultry pest prevalent during production that is capable of vectoring pathogens. This study was undertaken to determine the gut transit time of Salmonella for biosecurity risk analysis of pathogen dispersal into the environment. METHODS Adult and larval A. diaperinus were exposed to two concentrations of a fluorescently labeled ...
متن کاملEfeito da Temperatura e Cama do Aviário na Virulência de Beauveria bassiana (Bals.) Vuill. e Metarhizium anisopliae (Metsch.) para o Controle do Cascudinho (Alphitobius diaperinus) (Panzer) (Coleoptera: Tenebrionidae)
This study was carried out to evaluate the influence of temperature and poultry litter on germination vegetative growth virulence and conidial production of Beauveria bassiana (Bals.) Vuill. and Metarhizium anisopliae (Metsch.) isolates on larvae and adults of the lesser mealworm (Alphitobius diaperinus) (Panzer). The vegetative growth and conidial production were evaluated on culture media. Vi...
متن کاملTransient gut retention and persistence of Salmonella through metamorphosis in the lesser mealworm, Alphitobius diaperinus (Coleoptera: Tenebrionidae).
AIMS This study was undertaken to determine the retention of Salmonella through Alphitobius diaperinus metamorphosis and its contribution, through defecation, to external contamination. METHODS AND RESULTS Insects were exposed to a tagged Salmonella enterica and evaluated for external elimination. (i) Each day for 3 weeks, a filter collected frass from a restrained insect for analysis. (ii) E...
